It's official! Kanye West announced his girlfriend of eight months, Kim Kardashian, is pregnant with the couple's first child. 'Ye revealed the news onstage during his Atlantic City show on Sunday night, stopping mid-set to ask the audience to "make some noise" for his "baby mama."

And soon after a slew of fans tweeted the baby news, E! News confirmed the buzz with members of the Kardashian clan who then jumped on Twitter to share their excitement.

While sister Kourtney Kardashian said she wanted to "shout from the rooftops with joy," momager Kris Jenner played coy with a simple, "Oh BABY BABY BABY!"

In the latest season of E!'s "Keeping Up With the Kardashians," cameras captured Kim inquiring about and seemingly beginning the process of freezing her eggs for a future pregnancy. (Though viewers didn't see much beyond that.) She also discussed the ongoing complications of her pending divorce to basketball player Kris Humphries, to whom she is technically still married.

West and Kardashian might prove to be the most-watched pregnancy since Jay-Z and Beyonce revealed they were expecting on the MTV VMA stage in 2011; their daughter, Blue Ivy, turns a year old on January 7. With Kim K.'s reality TV prowess and Kanye's superstardom, the next several months are likely to play out in front of the cameras.

It is reported Kim is approximately twelve weeks along.
